REMOVAL & INSTALLATION
See Figure 1
- Relieve the fuel pressure from the system. Disconnect the negative battery cable.
- Remove the BPT valve and the bolts securing the fuel tube.
- Remove the bolts securing the injectors, then take out the fuel tube and injector as an assembly.
- Remove the injectors from the fuel tube.
- Install the injectors to the fuel tube. Always use new O-rings. Lubricate O-rings with a small amount of silicone oil.
- Install the injector/fuel tube assembly. Tighten the fuel tube bolts evenly to 12-15 ft. lbs. (16-21 Nm) and install the BPT valve.
- Start the engine, then check for fuel leaks around the injectors and fuel tube.
See Figures 2 through 19
- Relive the fuel pressure from the system. Disconnect the negative battery cable.
- Remove the 2 drain plugs (from both sides of the cylinder block) and drain the engine coolant into a suitable container.
- Disconnect the Automatic Speed Control Device (ASCD) and accelerator control wire from the intake manifold collector.
Disconnect the following from the intake manifold collector:
- Auxiliary Air Control (AAC) valve
- Throttle sensor and throttle valve switch
- Ignition coil
- EGR control solenoid
- Air regulator
- Exhaust gas temperature sensor (California models)
- PCV hose from the right-hand rocker cover
- Air duct hose
- Ground wire
- EGR Tube
- Purge hose from the evaporative canister
- Disconnect the brake master cylinder, pressure regulator and the remaining carbon canister vacuum hoses.
- Remove the intake collector.
- Remove the fuel hoses from the injector fuel tube assembly.
- Disengage the injector electrical connectors, then remove the injectors with the fuel tube assembly.
- Replace or clean the injectors, as necessary.
- Install the injectors to the fuel tube using new O-rings and insulators.
- Install all parts which were disconnected from the intake manifold collector, in the reverse order of removal.
- Connect the negative battery cable.
- Verify that the drain plugs are installed in the cylinder block, then refill and bleed the cooling system.
- Run the engine, then check for fuel leaks around injectors and fuel tube.
